Quote:Last night I had two hours before clouds came in. WooHOOO! Figured I'd practice the steps in the Polar Alignment. I am SOOOO loving being able to set up in such short order with the GEM!! With the Lx200 and the wedge, there's no way I would have set up last night, knowing it would be foggy & cloudy soon!!But anyway, on to my questionI started with the GOTO alignment and I used four stars. Then, after taht I got a great Polar Align done (I think) and I proceeded to cancel the Sync on the previous GOTO alignment. When I tried to redo the GOTO alignment, all it would ask me is do I want to replace a star? It doesn't get to a spot where you can just redo the star alignment? WHY?It asked if I wanted to replace a star. I did, and from then on my GOTO's were horrible. I don't understand why it just won't let you do another star alignment after you complete the Polar Align process.But I shut it off, and restarted the mount. Doing another 4-star alignment without touching the mount adjustments gave me very good GOTO's for about 5 minutes before cloud cover rolled in.So there are actually two questions: One, is the steps needed to make that transition when you complete the Polar Alignment and you want to cancel the Sync and do a star alignment. Why is it only asking if I want to replace a star?Next I want to fine tune my coordinates. When I got first light with the mount, I set it to San Diego from the list of cities and have never changed it. But last night I brought my GPS out to the scope & I wanted to update the mount to exact coordinates. After I entered the date & time into the mount, I pressed UNDO to try getting back to the menu where I could enter coordinates. The only option I got was to cancel. So please, what's the step I am missing here?Thanks for your help on all this stuff guys! By the time springtime comes and the weather is clear I'll know this mount like an expert and I'll be confident enough to bring the GEM out to the desert with the club. I can't wait to get it set up next to my LX200's pier and be able to image from both scopes at the same time!!

Quote:I have a Garmin and those are the coordinates that I will be entering. I need to figure out how though.
Quote: It's pretty simple actually. When you are setting up, scroll to "Custom Site". Then input your coords. They'll be saved until you change them or reestablish the "factory settings."
Quote:Every time I try to replace an alignment star after polar aligning, it gives me trouble. It lets me replace the first star fine, but causes trouble when I try to replace the second. Maybe I'm missing something (only second night out with the mount), but I just turn it off and back on, then align as normal and everyone is happy.A recent "dialog" between me and the HC after polar alignment recently was something like:HC: "Replace Caph?"Me: <selects Yes>HC: "Slew to Hamal."Me: "What? No! I already replaced Hamal." Me: <presses Undo, then Alignment Stars again>HC: "Replace Caph?"Me: <selects Yes>HC: "Slew to Hamal."Me: "Grrr..." <Slews to Caph anyway.>HC: "Slew to Hamal."Me: <reboots>What am I missing?
Quote:Also, why are you replacing alignment stars?When during the course of the evening are you replacing an alignment star?
Quote:I hope a future patch fixes this.

Quote:Hi-This is somewhat loaded, but it says you MAY need to re-align, but check the goto accuracy and see if it is needed. Although the mount does move during polar alignment, as long as the mount moves as it should to polar align, the GoTo accuracy should still be ok.Frank
Quote: That's why I asked the question earlier. If this is the case, then the mount doesn't compensate for the manual movement in Alt/Az. Or am I missing something?
Quote: Quote: That's why I asked the question earlier. If this is the case, then the mount doesn't compensate for the manual movement in Alt/Az. Or am I missing something? Hi-There is a related discussion ongoing in a similar thread - but basically AllStar knows how far off the polar alignment is (just use Align/Polar Alignment/Display to see the error in Alt Az) but the hc has no ability to physically move the mount in alt/az - which is what is needed to become physically polar aligned.So - it intentionally aims 'off' from the alignment star and asks a human to move the mount until the star is centered - at which point it assumes it is perfectly aligned.As long as the mount has been moved cleanly in alt/az motions of the correct distance, AllStar knows how the mount is now aligned against the sky and can do GoTo's directly.If there were big motors to move the equatorial head in alt/az, the hc could do it all by itself - but it uses a human instead.After the alignment, the displayed polar alignment error is 0,0 - since it assumes it is now perfectly polar aligned and it has no other information to go by unless someone replaces alignment stars - at which point those errors will show as non-zero, but hopefully small values.Frank
